Of course it is. That why we East Asian are assume to have a smalll , penis . Those subcontinent Indian and Arab people have it big. Black guy are suppose to have it bigger that white guys. It have something to do with your race.

By the way, Red Bull what up with all this dick size stuff. Just now is Mandingo , now this........what do you have in mind.

I must restrain myself. Last year I was dating a Harvard and Brown professor of bio-statistics. My background in econometrics let me keep up with most of the statistics, but his work is with teams exploring cancer genetics. So in order to be able to have any clue about what he did at work, I spent part of last summer reading genetics text books. The result of my homework:

Genetics almost certainly plays a role in any feature of our anatomy. But not in a deterministic way. Any single trait is usually affected by multiple genes. Then there are the genetic factors that determined which combination of genes will be expressed as well as the environmental (epi-genetic) factors that affect gene expresion, and are only beginning to be understood, but which seem to have significant influence on how organisms develop, live and die. Finally there are the factors that practically speaking are not genetic but affect physiology - maternal nutrition, maternal health, post birth nutrition and environment, etc, etc.

So, sure genetics probably does play a role in penis size, but how much of a role and how is unlikely to clear any time soon.

Remember we get half our genes from our mother. I resemble my maternal grandfather more than my own father. I have four sons and my second son has a larger penis then the others. I guess he got the recessive gene.

What the hell did all that mean??? Did this professor have a big schlong or not? And what did it prove about heredity? Apparently a background in econometrics means you entirely lose the ability to remain even remotely on topic.

It boils down to natural selection - attracting mates of the opposite sex with which to reproduce. A recent documentary on sexual evolution posited that women would select mates with larger penises as they were perceived to be more fertile. If it weren't for this natural selection human males would have much smaller penises - cited were the small penises (relative to both human males and their own overall size) of gorillas and other primates. Btw, this is why human females have proportionally larger breasts than apes - breasts developed to mimic the ass to attract men when humans began walking upright. Makeup is used for the same effect, i.e. lipstick draws attention to lips which mimic the vag.

but that doesn't mean if your father was huge you will beor visa versa

genetics on something as complex as penis size will be multifactorial and needs to take in influences from the maternal side as well

You are so right in bringing up the maternal side of the coin. There are some things such as baldness and color blindness that come primarily from the maternal side. It would be interesting to know if penis size can come from either side of the parental gene pool (luck of the draw) or if it does primarily come from one or the other.

Spent quite a bit of time studying this and other genetic curiosities, like the debate over whether there is a "GAY" gene (you know if they ever bring back eugenics some will be looking to abort GAY fetuses). Certainly will be an interesting debate and might make quite a dilemma for the right-wing, anti-gay, gay=sin religious folks vis a vis their abortion stance. Wooh!

The research so far has only yielded one broad statistical truth that passes the necessary tests of correlation: the more male children a woman has, there is a statistically significant increase in the % turning out to be gay. This gives credence to the much more complicated model that it is not a single gene, nor necessarily a combination of genes, but that hormones in gestation (1st trimester) play a large role. In evolutionary terms, it makes sense that if too many males are being born, nature might try to compensate for the increased competition for mates with which to procreate. Just an interesting theory at this point.

As far as penis size goes, they have established a link between the "growth hormone" receptors in the penile tissues (GH, IF-1, IGF-1, and a host of others) together with the amount of male androgens produced and bio-available in the body of the mother early in the pregnancy. Theoretically, an "ideal" combination of genes from the father favoring larger size, also resulting in an excess of penile growth receptors, an excess of bio-available testosterone androgens in the mother as well as possible hormonal factors affected by repeated or the first pregnancy with male offspring would have to create a "perfect storm" of factors to develop an extraordinarily large penis (more than 3 standard deviations above the mean values for length & girth).

Genetics definitely plays some role, but the proteins they generate have a multitude of functions, including a "turn off" role that accounts for the ending of further development in many areas.

As a gay man, I have fantasies (like most of us) and one I like to play with IN MY HEAD assumes a scenario where these complex interactions and genetic, hormonal & other factors had all been sorted out for penis length and girth, as well as testicle size (by the way, check out "fragile-X syndrome" as well as macroorchidism & macrophallus to see what side effects bio-engineering might have on the rest of the human life). I like to fantasize about "breeding" for male offspring afflicted with a syndrome where the penis and testicle develop early (see: precocious puberty) and continue to enlarge without ever fully developing the other puberty attributes (except perhaps the fusing of the growth plates at a height of 6' 7").

I then imagine the middle & high school gym classes of these boys where their flaccid size of 7-9" arouses the attentions of male friends, coaches, teachers, the school nurse etc. I imagine the pediatric visits, ultimately yielding the need for design of a spandex "truss" to support the weight of the testicles, each of which could approach 1/2 pound, and the choice of underwear and clothing to help conceal the condition and reduce discomfort from the sheer weight of all that "junk." I picture the size factor as slowing down around the age of 22, with a length of 14-15", a plum-size glans and girth at the "base" (when erect) of 9-10" around. The fun stuff is imagining the normal experiences of life (family trips to the beach, camping, hiking, etc) as well as athletics, and visits to extended family where younger male cousins have to share their space with someone like that, and the "shock and awe" that would accompany observing a member larger than any seen before.

Well, it's a nice JO fantasy, but in real life I deal with what nature gave me.

And this is why even in today's Germany gays are not entirely comfortable with the "gay gene" theory, as that would mean that Hitler would have had a "valid" reason to slap the pink triangle on our predecessors and ship us off to the camps.

As far as the OP goes, no idea. I have never seen my dad's or brother's stuff. Eww...
